PAVING-BLOCK CONSTRUCTION.

Specification of Letters Patent.

Patented Feb. 22, 1921.

Application filed August 11, 1919. Serial No. 316,802.

To all whom it may concern:

Be it known that I, GEORGE WV. VVAR- MOUTH, a citizen of the United States, and a resident of Indianapolis, county of Marion, and State of Indiana, have invented a certain new and useful Paving-Block Construction; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like numerals refer to like parts.

This invention relates to the means and method of securing wooden pavement blocks to their base or foundation for securing them in position thereon, and permitting their expansion and contraction due to the elements so as to prevent buckling of the pavement, and it is the object of this inven tion to overcome this disadvantage of constructing pavements from wooden blocks.

One feature of the invention is the means for securing the blocks .to their base, which consists of a V-shapedmetal strip slidably inserted in theblocks and securedto the base by bolts, staples and thelike.

Another feature of the invention is the method of securing the blocks wherein they will be slidable longitudinally and laterally so as to compensate for any expansion or contraction. This is accomplished by the adaptability of the blocks to slide laterally upon the metal retaining strip, and securing the strip to the base through a slot whereby the strip may move bodily sidewise and permit expansionin that direction.

Another feature of the invention is the construction of the side members or guards bordering the pavement, which are likewise slidably secured so as to yield with the expansion of the blocks. This construction permits of the pavement of board walks.

bridges and the like so that there will be positively no bucklingof the surface. This construction. is also applicable and advantageous for use informing patch blocks suitable for patching holes in street pavements, covering manholes and forming platforms for workmen and other like constructions.

Referring to the "drawings, whichfare made a part of this application, Figure 1 is a plan view of a wood block surface patch. Fig. 2 shows a side view of the patch in Fig. 1. Fig. '3 isan' enlarged view of the section taken on line 3-3 at F ig. 1. Fig. 1 is an enlarged view of the section "taken on the'linest eof Fi'g. '1. "Fig. "5 isa modified form of a patch similar to that shown in Fig. 1. Fig. 6 is a side elevation of the view shown in Fig. 5. Fig. 7 is an enlarged section taken on the line 77 of Fig. 5. F ig. 8 is an enlarged section taken on the line 8 8 ofFig. 7, with portions broken away. Fig. 9 11s a plan view of a board walk construction. Fig. 10 is a section taken on the line 10-10 of Fig. 9. Fig. 11 is a section taken on the line 1111 of Figf 9. Fig. 12 is an enlarged view showing the means for securing'the metal retainingstrips. Figs. 13, 14:. 15 and lfishow modified forms of means for retaining the metal strip. Fig. 17 shows a modified form of paving blocks with the metal retaining strip. Fig. 18 is an end View of a modified form of metal retaining strip. F 1g. 19 is a plan view of the strip shown in Fig. 18. Fig. 20 shows a portion of a plan view of the approach for a bridge'run way. Flg. 21 shows a side elevation same as shown in Fig. 20.

In the drawings there is shown a broken away portion of a pavement 10, whichmay be originally of block, asphalt or any other like substance, in which it is'desiredto place a temporary patch, or a removable manhole or block platform. To temporarily patch the pavement until a permanent patch may be placed therein, a frame 11 is provided, preferably made of metal which is provided with outwardly extending horizontal flanges and vertical side members with a supporting bottom 12. The bottom 12 is provided with slots 13 through which the pins 15 extend for securing the V-shaped metal retaining strips 16 thereto so as to be rigidly secured to the bottom of the frame, but laterally slidable therein. The retain- .lng strips are adapted vtoextend laterally through the wooden paving blocks 17 so as to retain them within the frame 11 and prevent their removal therefrom, at the same time permitting said blocks to slide longitudinally of the reta ning strips so as to give with their expansion due to theelements. The blocks arefirst secured together and two diagonally disposed slots cut in them and then the retaining strip 16 is slid through the slots so as to secure the blocks in their proper relation to each other, the whole being placed in a frame. and the strips bolted through the slots 13 in the bottom thereof. By means of this construction the blocksare permitted to slide laterally of each; other or longitudinally of the strips,

and expand longitudinally of each other causing the strips to slide laterally on the bottom of the frame due to the slots 13.

This construction enables a wood block floor or patch to be made so that the 0X pansion will not buckle the pavement and the patches can be removed therefrom wherein it may be used over again and be more lasting than the patches now employed. Such a block adaptable for use as a etch in pavements at that time of year when a permanent patch cannot be put in, and may be removed upon the permanent patch being placed and use 1 over again, thereby saving a great deal of expense and labor. This construction may also be used for manholes in street pavements and bridges and the like, and for platforms for individuals to stand on.

Figs. 5, 6, 7 and 8 show a modified form wherein the bottom 12 of the frame is omih ted, and the retaining strip 16 is secured at its end to the side members of the "frame by turning their ends 18 and flattening them against the outside of the frame so as to secure the strips in position. This construction will permit of the blocks sliding longitudinally of tie strip, but it will not permit of the strip sliding within the frame and, therefore, is practical only in small constructions and indoor work where the expansion will not be great enough to cause the blocks to buckle.

Figs. 9, 10 and 11 show bridge or board walk construction which enables a pavement adaptable for that type of work, to be made of wooden blocks wherein the expansion would be compensated for so as to prevent the usual bucklin oi the blocks. A wooden base flooring 20. formed of planks is pro vided to which the blocks 1'? are secured by means of the strips 16, said strips being secured to the flooring by the belts or pins 14 extending through the slots formed between the planks, as shown in Fig. 11, whereby the strips may be secured on the planks and slide longitudinally thereof. The border or guard 21 is secured to the flooring by the bolts 22 extending therethrough and between the planks above mentioned, whereby the guards 21 may yield laterally when the exertion due to the expansion of the blocks is applied. By means of this construction there is no possible way of expansion of the blocks to cause them to buckle, and they are at all times held socurely upon the floor.

The metal retaining strips 16 may be secured by any suitable means, such those shown in Figs. 12, to 16 inclusive. In Figs. 13 and 14 the head 115 of the bolt 114- is elongated so as to retain its length and per mit the blocks to slide laterally upon the strip. In Fig. 15 a spring securing means 116 is used, which be extended through a hole or crack in the floor and hooked on the strip after the strip and block are in place. The spring securing means 117, shown in Fig. 16, may be applied after the blocks and strips are in place by pushing the spring through the slot provided in the flooring and between adjacent blocks until the ends thereof clamp over the edges of the strip, and then a wire 118 may be inserted through the s pijiing and under the flooring.

Figs.'18 and 19 show a method oi flattening out the ends of the metal. strip by cutting them partly to the center so as to form a locking member 119 for securing the ends oi the strip after the blocks are mounted thereon and preventing their removal there- .irom.

Fig. 17 shows .a side of the blocks provided with grooves n3 extending vertically on one side thereof so as to lie adjacent the abutting block and directly over the V shaped strip 16, in which tar or some plastic filler may be poured for sealing the blocks together and held. in the grooves by the trough of the strips 16 so as to prevent the escape thereof, for sealing the blocks together and upon said strip.

Figs. 20 and 21 show a means of forming a removable unit approach 120 adapted to be mounted on the ends of runways 121 for bridges and the like so as to dovetail with the end blocks. The approach units 120 may be formed and installed on the runways so as to eliminate the necessity ofbuilding up the bridge.

The invention claimed is:

1. A. pavement formed of paving blocks, means for slidably retaining the blocks together, means for supporting said pavement, a border guard mounted on said supporting means adjacent the blocks on the side of said pavement, and means for slidably securing said border guard to said supporting means for preventing its dislodgment there -from and permitting its expansion with the relative expansion of said blocks.
